Getting stuff published...

I like to write fantasy short stories, and plan on, some day soon, writing a fantasy novel. The only thing is, I don't have the slightest clue on how to get any of my work published, beyond the non-profit online publishing. I am a member of The Poster Board Kingdom at: http://www.fantasynews.net/pbk and so far that is where I have been able to quench my thirst for writing. But I want to do more. Any advice?
